Mezzanine floor fire protection is the most important task to determine correctly when considering a mezzanine floor, old or new. When a new mezzanine floor is installed by us we always liaise with Building Control to ensure that the correct level of fire protection is carried out on the steel structure. You may think that steel is pretty strong which it is, but in a fire the steel will tend to twist and deform at not very high temperatures and there are several reasons for this.
The effects of fire on a steel mezzanine floor structure
The steel sections that are used in the construction are in themselves very strong but will have been formed from flat sheet steel and either rolled or welded to form the sizes required. Heat on steel anneals or softens the steel which wants to convert to its pre-stressed state. The effect of this is that the whole floor structure twists and due to the weight of the floor, what is on the floor and the steel the whole lot can come crashing down quickly.
All of our steel structures are calculated, and often have triangulation steels in the corners of the floor to prevent twisting in just loading conditions, so the design needs to be calculated properly.
Mezzanine floor fire protection – Suspended Ceilings
Contrary to popular belief and pure incompetence by many of our competitors there are actually very few suspended ceiling types that are fully tested with a specific suspended ceiling tile to give the 1 hour fire protection required by Building Regulations. Some mezzanine floors which are small in proportion to a building and maybe are just used for occasional light storage may not actually require any protection as there is actually no perceived danger to employees and staff. 99% of floors will need mezzanine floor fire protection.
There are a few advantages of using a suspended ceiling over a plasterboard one, the main one is you can hide the services inside it. It is also a finished product without the need for skimming or painting. It can also provide sound performance preventing noise from the ground floor going through the floor. It is also quick to install.
We visit many installations carried out by others where the cheapest ceiling tile has been used, and the cheapest grid, and there is absolutely no way that the suspended ceiling is fire rated and we have to advise the customer of this fact.
